Abstract

L'INVENTION CONCERNE UNE POMPE D'INJECTION DE CARBURANT ET UN DISPOSITIF DE COMMANDE DE PLONGEURS POUR CETTE POMPE. CETTE POMPE 12 COMPREND UN ROTOR 18, UN ELEMENT DE POMPAGE COMPRENANT UN PLONGEUR 38, UN ELEMENT 20 ACTIONNANT L'ELEMENT DE POMPAGE, UN ELEMENT LIMITANT LE MOUVEMENT MAXIMUM DE CE DERNIER ET CONSTITUE D'UNE LAME DE RESSORT DONT UNE EXTREMITE LIMITE LA COURSE DE POMPAGE MAXIMUM, DE MEME QU'UN ELEMENT DE COMMANDE FIXANT CETTE EXTREMITE DANS UNE PREMIERE POSITION RADIALE DANS UN ETAT DE FONCTIONNEMENT DU MOTEUR, POUR LA DEPLACER DANS UNE DEUXIEME POSITION RADIALE DANS UN ETAT DE FONCTIONNEMENT DIFFERENT. L'INVENTION EST UTILISEE POUR ASSURER L'ALIMENTATION DE CHARGES SUCCESSIVES DE CARBURANT A UN MOTEUR A COMBUSTION INTERNE.THE INVENTION RELATES TO A FUEL INJECTION PUMP AND A PLUNGER CONTROL DEVICE FOR THIS PUMP. THIS PUMP 12 CONSISTS OF A ROTOR 18, A PUMPING ELEMENT INCLUDING A PLUNGER 38, AN ELEMENT 20 ACTING THE PUMPING ELEMENT, AN ELEMENT LIMITING THE MAXIMUM MOVEMENT OF THE LATTER AND CONSTITUTES A SPRING BLADE OF WHICH ONE END LIMITS THE STROKE OF MAXIMUM PUMPING, AS WELL AS A CONTROL ELEMENT FIXING THIS END IN A FIRST RADIAL POSITION IN AN OPERATING STATE OF THE MOTOR, TO MOVE IT IN A SECOND RADIAL POSITION IN A DIFFERENT OPERATING STATE. THE INVENTION IS USED TO ENSURE THE SUPPLY OF SUCCESSIVE LOADS OF FUEL TO AN INTERNAL COMBUSTION ENGINE.
